Parameters

x

A double that represents a dividend. [Edit]

y

A double that represents a divisor. [Edit]

Returns

A double whose value is as follows:

Value	Description
x - (y Q),	Q is the quotient of x/y rounded to the nearest integer (if x/y is exactly halfway between two integers, the even integer is returned).
+0	Q is the quotient of x/y rounded to the nearest integer (if x/y is exactly halfway between two integers, the even integer is returned), x - (y Q) is zero, and x is positive.
-0	Q is the quotient of x/y rounded to the nearest integer (if x/y is exactly halfway between two integers, the even integer is returned), x - (y Q) is zero, and x is negative.
double.NaN	y = 0.

[Edit]

Remarks

This operation complies with the remainder operation defined in Section 5.1 of ANSI/IEEE Std 754-1985; IEEE Standard for Binary Floating-Point Arithmetic; Institute of Electrical and Electronics Engineers, Inc; 1985.

Note: For more information regarding the use of +0 and -0, see Section 3.1 of ANSI/IEEE Std 754-1985; IEEE Standard for Binary Floating-Point Arithmetic; Institute of Electrical and Electronics Engineers, Inc; 1985.

Example

The following example demonstrates using the Math.IEEERemainder(double, double) method.

C# Example

using System; public class MathIEEERemainderExample { public static void Main() { Double d1 = Math.IEEERemainder(3.54,0); Double d2 = Math.IEEERemainder(9.99,-3.33); Double d3 = Math.IEEERemainder(-9.99,3.33); Double d4 = Math.IEEERemainder(9.5,1.5); Console.WriteLine("Math.IEEERemainder(3.54,0) returns {0}", d1); Console.WriteLine("Math.IEEERemainder(9.99,-3.33) returns {0}", d2); Console.WriteLine("Math.IEEERemainder(-9.99,3.33) returns {0}", d3); Console.WriteLine("Math.IEEERemainder(9.5,1.5) returns {0}", d4); } }

The output is

Math.IEEERemainder(3.54,0) returns NaN
Math.IEEERemainder(9.99,-3.33) returns 0
Math.IEEERemainder(-9.99,3.33) returns 0
Math.IEEERemainder(9.5,1.5) returns 0.5
